| 英文摘要 | the influence of the addition of n-type semiconductor oxide ceo2 and noble metal pd to ni/gamma-al2o3 catalyst on carbon deposition by ch4 and carbon elimination by co2 was studied by using a pulse microreaction as well as bet, tpr, co2-tpsr and hydrogen chemisorption techniques. it was found that, the addition of n-type semiconductor ceo2 to ni/gamma-al2o3 catalyst could decrease carbon deposition activity of ch4 and increase carbon elimination ability of co2; the addition of noble metal pd could further alter the interaction between support al2o3, promoter ceo2 and active phase ni, as a result, the performance of resistance to carbon deposition of ni/gamma-al2o3 catalyst was improved. at the same time, a new explanation for the above promoting effect was put forward by the models of carbon deposition by ch4 and carbon elimination by co2 on the ni-ce-pd/gamma-al2o3 catalyst. |
